DRAFT-EQUALIZER.

sPEGIFIGATION forming part Of Letters Patent NO. 646,965, dated April10, 1900.

' Application filed June 13, 1899. erial No. 720,435. (Nifmodel-l T0(LZZ whom it may concern:

Be it known that 1, CHARLES FERM, a citizen of the United States,residing at Lindsborg, in the county of McPherson and State of Kansas,have invented a new and useful improvement in equalizing the draft uponthree horses that walk abreast in the pulling of a self-binder orharvester-machine, of which the following is a specification.

\Vhen three horses are used to work abreast in the pulling of aself-binder, one horse walks next to the grain and two horses on the OEside from the grain. By the off side I mean the side of the tongue thatis away from the grain. On a right-hand cut the off side is to the leftof the tongue and on a left-hand cut the off side is to the right sideof the tongue. The sickle or knife that cuts the grain extends six feetor more beyond the near horse. The resistance of the grain upon thesickle tends to pull the tongue to-' ward the grain. This sidewisepulling is called side draft. The grouping of two horses on the off sidewhen at work tends to aggravate this side draft. The usual method atpresent employed by manufacturers of harvester-inachines is to adjustthe tongue as close to the knife as possible. This again throws the nearhorse right onto the side of the grain to be out, making the double orsingletree to extend into the grain beyond where the horse walks. Whennow the off team steps up and the near horse steps back, this movementthrows the singletree of the near horse into the reel that gathers thestanding grain upon the knife or sickle there to be cut. This throwsforeign matter upon the reel, which is thereby endangered to beingbroken. To prevent breakage, there is a catch knob or notch on leverattached to doubletrees and tongue, intended to catch on the tongue toprevent the slipping back of the near horse into the reel, so as to savethe reel from being broken. This catching on tongue throws all the workon one team, doubles the side draft, and breaks the neck and shouldersof the horses. Having the fulcrum of draft attached to the top or upside of the tongue adds neck weight to the horses.

All harvester-machines are now so made and adjusted that when idle, withman in seat, there is an even balance, (when the machine is evenlybalanced.) When the ma chine is at work, in order to do good work it isnecessary to tilt the machine forward in order to get an even elevationof the grain. This adds weight on the necks of the horses, called neckweight. To take away this neck weight, it is necessary to have pullingapparatus below or underneath the tongue.

My invention relates to the enabling of the manufacturer to so attachthe tongue to the machine that the near horse can have free play to stepback and forth in his work with out endangering the reel, and thus totake away, first, the catch on tongue; second, the side draft; third,the neck weight, and, fourth,

, to enable the operatorto adjust the machine I I attain these objectsto the work to be done. by the mechanism illustrated in the accompanyingdrawings. v

Figure 1 isatop view of the entire machine. Fig. 2 is an end view. Fig.3 is a side View of block 2. Fig. 4 is a side View of block 4. Fig. 5 isa top view of filler 8.

The self-binder and harvester is not shown, neither are the horses. Wemust suppose their places to be filled for the purposes to be attained.

The invention connects only direct with the tongue A, brace 13,spreaders C D, doubletree E, and singletree F.

Similar letters refer to similar parts. All letters refer to partsbelonging to the harvester-machine.

All figures refer to those parts which are my invention. Similar figuresrefer to simi lar parts throughout all the views.

By extending the draft from the center of the tongue by stationary andperforated extension I, made fast to brace 13 by bolt through brace B,by block 2, fastened unto extension I by bolt,'by pulley 3, playing inblock 2, by hook 7, playing in said block 2, by chain 6, fastened tohook 7 and playing over pulley 5, which again is playing over bolt insaid block 4, being fastened by bolt to spreader D and doubletree E byagain chain 6, running under tongue and over pulley3 in said block 2,running up and attached to clevis 9,which again is fastened or attachedto spreader O and singletree F, spreaders (l and D being fastened attheir inner ends to tongue, as set forth. This takes away all sidedraft,

all neck weight, all catch on ton gue,and equalizes the work upon thethree horses alike, permitting them to Work easy back and forth.

1 is a straight perforated piece of iron attached to tongue A and brace13, as shown in the drawings. It serves the purpose of moving thefulcrum from the center of the tongue to the center of the weight to belevered.

2 is a block to be attached to extension I, and is adjustable thereon asthe work of the machine requires such adjustment.

4 is a block, as shown in Fig. 4, with pulley 5 therein, attached todoubletree E and spreader D.

6 is a chain attached to hook '7, (see Fig. 3,) as appears in Fig. 1 bydotted lines under tongue, running over pulley 5 in block 4, againrunning under tongue and over pulley 3'in block 2, running under brace Bup'to clevis 9 and attached thereto, which again is attached to spreaderO and singletree F. This connects all parts and serves as'the connectinglink between all parts of the invention.

9 is a common clevis and serves the purpose of connecting chain 6'tospreader O and singletree F.

10 are four large links attached to chain 6 and hanging loose underneathclevis 9, as shown in Fig. 2. These links serve the purpose oflengthening the chain when that is required by the extension of thedraft away from the tongue as the work of the machine requires suchadjustment.

8 is a filler between extension I and brace B. It serves the purpose ofa rest for extension I, with bolt through it. Extension I and brace Bmake it rigid and, through extension 1, tongue A, and brace B, transmitthe pull to the self-binder or harvester-machine.

The principle of the working of my invention is to transmit the pull tothe harvestermachine direct from brace B and through said brace B totongue A, and through tongue A keeping the self-binder in the rightposition, thus getting the pull the closest possible to the work to bedone.

All the parts described are connected together and cooperate to producethe useful results.

I claim- 1. In draft-equalizers, a pole A provided with a stationary andperforated extension I, a block 2 attached thereto having a pulley 3therein and hook 7, attached or made fast in said block, a chain 6,attached to said block 2, at hook 7, running over pulley 5, in block 4,said block 4, being attached to doubletree E, and spreader D, at itsouter end, its inner end being attached to pole A, said chain 6 running'over pulley 3, under tongue A, and brace B, to clevis 9, and attachedthereto, which clevis is again attached to singletree F and spreader Oat its outer end which again is attached to pole A, at its inner end,all combined as set forth.

2. In draft-equalizers, the pole A, carrying a perforated extension I,attached to brace B, and supporting-block '2, which is adjustable onsaid extension, said block 2, carrying a pulley 3, and hook 7, a chain 6attached to'said hook, a block 4, having a pulley 5 therein attached topole A, through spreader D, said chain 6, playing over pulley 3, toclevis 9, said clevis 9, having adjustable links 10, attached theretofor adjustable purposes said clevis 9, being attached to chain 6,spreader O, which again is attached to pole A, and again attached tosingletree F, all combined as set forth.
